For Pregnant Women

The Harmony Prenatal Test is a DNA-based non-invasive prenatal test (also known as a non-invasive prenatal screen “NIPS”) for Down syndrome (trisomy 21), trisomy 18 and trisomy 13. It is proven to be more accurate than traditional screening tests and can be performed as early as 10 weeks of pregnancy.The Harmony Prenatal Test can also report fetal sex, screen for sex chromosome conditions and 22q11.2 deletion.

The greater accuracy and low false-positive rate of Harmony compared to traditional tests may minimize the chance that further testing would be recommended due to a false-positive result.1
